For question 8 here are my reasons.
a) 1 is infact a switch, not a router.
b) as it's only forwarding data, it's a hub
c) a router is used to connected networks to networks, so in this case, it would be used to connect the internet to the H.D. LAN and the L.H. Lan
d) nfi what that is, some kind of token ring bs.
The anwer is C
btw, this is his bro if anyone cares. this exam was full of shit.
also, question 20 is the most bullshit thing i have ever read. seriously, what the hell. I'm doing CISCO at tafe (i have to keep going with it till the end of the year ffs) and that shit made no sense.
Correct me if im wrong, but parity bits do not determine whether or not the IP is static or dynamic.
Excuse the swearing, im slightly drunk and annoyed at these questions.
q15 is C. Irrespctive of whether or not the speakers are any good, think of it as a radio. it's transmitting data through wireless and there is a 100% chance of anything going wrong. How to use my networking nerdology. As most of you know there is TCP and UDP. TCP is a connection based thing where in order to send data, a handshake must occur. UDP is connectionless, meaning that data is sent, regardless of whether or not the user recieves it.
If the streaming was to occur via TCP and data was dropped, the phone would require the data to be resent, thus it would take a long, long time. UDP however, allows for this minor loss of data so that although not all info is sent, enough is sent to get the jist of whats happening.
Most of you guys have used Vent or Teamspeak, or any some form of voice client, even games too. Those lag spikes/dropouts? Those are via UDP. Ever noticed how sometimes you'll miss what someone has said. Thats because UDP doesnt resend data, where as TCP does.
It's got nothing to do with the speed of the server, electromagnetic interference or the speakerphone itself, its the way the data is transmitted in the first place.
